What does rollback mean? Is this coin completely dead or what?
Rollback... well, imagine this... they found a mistake in the blockchain, that cause for example that some coins were hacked from the block 5... (just an example) so what they do, all what was mined after block 4 dissapear and we return to block 4 starting all this again... as they have the system centralized they have all the domain of manipulate the blockchain (and im not agree with it)... so we are the one who pays the consequences...
What annoys me is that is the second time, the system is stopped until i dont know when... and besides they dont consider to even report this in other place only telegram... something this important... really... no explanation no nothing... sorry for complain but just i dont get it....
Everything done after that block is not longer valid... sell, mine etc... so is like fork a new coin from the old one.. so all the costs of electricity for mining, sells on x price.. is for nothing...
